Final answer:
Halfway through the Ferris wheel's rotation (after 16 seconds), the rider would be at the lowest point, which is 27 meters below the starting top position.
Step-by-step explanation:
The student's question regarding the vertical position on a Ferris wheel after 16 seconds relates to circular motion in physics. Given that the Ferris wheel is 27 m high and completes one rotation every 32 seconds, we can deduce that halfway through a rotation (after 16 seconds), the rider will be at the lowest point of the wheel.
This is because the wheel rotates in a counterclockwise direction, and starting from the top, 16 seconds corresponds to half of a full revolution (180 degrees). The vertical position will therefore be directly at the bottom of the wheel's vertical diameter, which is 27 meters below the starting position at the top.
